Kakao 도서 API에서 header값을 넣어줄 때 문제가 생긴듯 하다..

 

body 부분을 확인하자.

{"errorType":"AccessDeniedError","message":"cannot find Authorization : KakaoAK header"}

 

header가 잘못들어가 있었다.!

public class KakaoClientConfiguration {
    @Bean
    public RequestInterceptor requestInterceptor(@Value("${external.kakao.headers.rest-api-key}") String restApiKey) {
        return requestTemplate -> requestTemplate.header("Authorization", "KakaoAK " + restApiKey);
    }

    @Bean
    public KakaoErrorDecoder kakaoErrorDecoder(ObjectMapper objectMapper) {
        return new KakaoErrorDecoder(objectMapper);
    }
}

• 이렇게 config 설정을 통해 "KakaoAK "을 자동으로 넣어주는데
• rest-api-key를 넣어줄 때 KakaoAK efksdfksfklsjfdklsfjkl 이렇게 넣어버린 셈..

원인은

테스트 코드 실행 시 올바르지 않은 header값을 넣었기 때문
